Having problems with your Buick Century ?
MY Buick Century that I purchased sat for like 3 years without been driven. I did a tune up which consisted of oil change, and plug change. I did not change out my wires and change the coil pack(3).. My car has started to run rough and sound like it is sick. What are some solutions. Could this be coilpack and wires.??
With the vehicle having set for three years without having been driven, running rough or rough idle could be anything. Did you inspect the spark plug wires thoroughly to make sure there were not damaged? Did you drain the old gas and replace it with new? Are are you getting a check engine light? There are some simple steps to test the coil pack and here's an easy one
I would say its a fuel problem. You can try replacing the fuel filter, but there may be foreign matter in the tank and in the injectors.
